MAINTENANCE AND REPAIR INSTRUCTIONS
Rechargeable Flashlight
Warnings: Any battery may leak harmful chemicals which may damage skin, clothing,
or the inside of the flashlight TO AVOID RISK OF INJURY, DO NOT LET ANY MATERIAL
LEAKED FROM A BATTERY COME IN CONTACT WITH EYES OR SKIN. Any battery may
rupture or explode if put in a fire or otherwise exposed to excessive heat. TO AVOID
RISK OF INJURY, DO NOT EXPOSE BATTERIES TO EXCESSIVE HEAT.
INSPECTION AND MAINTENANCE
Battery Pack - Remove the battery pack from the flashlight and visually inspect for
signs of gas or chemical leakage. Indications of leakage are discoloration of the plastic
sleeve or white fuzzy material near the top (positive side button) of each cell. Another
indication would be a bulging deformation of the bottom (negative flat end) of the cell
can. If any of these signs are observed the battery pack should be removed from
service to prevent chemical damage to the inside of the flashlight.
Electrical Contacts - The bare (bright) metal surfaces between the tail cap and barrel
must be clean as well as the spring contact surface of the tail cap.
O-ring Seals and Screw Threads - To keep seals from drying out and the threads
operating smoothly, apply several drops of clean petroleum oil or jelly.

(15) will stay in the BARREL (16) when it
is unscrewed. If this happens do the
following:
A. CHARGE MODULE METER SETTINGS
Meter reading is .005 –.764 mA. A bad
module will register .000 or 1 mA.
A. METER SETTINGS
Dial should be at 2k Ωohms.

CHARGER MODULE TEST

Rechargeable Flashlight
MR Rev.1 8/03 421-000-438
10
After you have removed the silver ring and
insulator ring you will see the flat surface
where the rings had been.
Try to unscrew the MODULE (15) without
damaging the flat surface or the threads. Use
a pair of pliers and a rubber band, grip the
flat surface as gently as possible and
unscrew the MODULE (15)
(counterclockwise).
PROBLEM (cont.)
Separate the silver ring and black insulator
from the MODULE (15) by inserting your
finger nail or a knife blade between the ring
and the second insulator. The ring is held in
place by the spring loaded diode shown
next to the top thumb.
The diode shown in the picture is attached to a
spring and insulated by a plastic sleeve. In this
picture the sleeve is not shown and is still in
the diode hole of the MODULE (15).
Occasionally the diode might fall out when you
are unscrewing the MODULE (15), note how it
goes back into the hole and MAKE SURE THE
PLASTIC SLEEVE IS IN PLACE. A severe SHORT
will occur if the sleeve is missing.

Before replacing the plastic insulator note
the lip on one side of the insulator ring.
The lip on the insulator ring goes against the
silver ring so that the flat side will be facing
out. It will snap into place.
When replacing the ring onto the MODULE
(15) place the ring over the diode pin, push
down and snap the ring in place.
STEP 13
Push the HEAD (14) down and over the
O-RING (10) and remove it from the SWITCH

the rear of the SWITCH HOUSING (9).
FIGURE 2
If the push button is up, use a ball point pen
or pencil and: Push the button down and at
the same time push the entire mechanism
out the back of the housing.
When you remove the pen the button
should be locked under the housing as
shown in figure 1.
STEP 14

STEP 29
Hold the REFLECTOR (6) down with your
thumb as you hold the HEAD (14) with your
fingers as shown. This allows you to hold
the REFLECTOR (6) down and turn the HEAD
(14) for adjustment.
STEP 30
Using a pencil eraser and with the light OFF,
center the LAMP) (11) in the REFLECTOR (6)
hole. DO NOT TOUCH THE REFLECTORS
SURFACE or TRY TO CLEAN IT WITH
ANYTHING.
STEP 28
BULB ALIGNMENT
Before replacing the FACE CAP ASSEMBLY
(5) check for proper bulb alignment.
Using a test REFLECTOR (6) place it into the
head as shown.
STEP 31
While still holding the REFLECTOR (6) in the
HEAD (14) turn on the light, put it in spot
mode and observe the spot pattern. If the
LAMP (11) is aligned properly you should see
